Leo Yan 995527db41 perf stat: Fix use-after-freed pointer detected by the smatch tool 
[ Upstream commit c74b05030e ]

Based on the following report from Smatch, fix the use-after-freed
pointer.

  tools/perf/builtin-stat.c:1353
  add_default_attributes() warn: passing freed memory 'str'.

The pointer 'str' has been freed but later it is still passed into the
function parse_events_print_error().  This patch fixes this
use-after-freed issue.

README 

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
